Patent GB-1464544-A (GB)
IPC: G03G15/05
Filed: 1973-05-21
Abstract: 1464544 Image converter tubes AGFAGEVAERT 8 May 1974 [21 May 1973] 24168/73 Heading H1D An electron discharge image in an evacuated envelope-produced, for example, by the incidence of an X-ray, ultra-violet, visible, or infrared image, corresponding to scanned information, on a photocathode 50-is recorded as an electrostatic charge image by accelerating it through a channel electron multiplier 51 on to an electron penetrable window or windows 57 forming part of the wall of the envelope of the device; the electron image passing therethrough either forms a charge pattern directly on an electrically insulating receiving material, which is moved in synchronism with the information scanning, or produces ionization in a gaseous atmosphere separating the window or windows from the charge receiving material. The window portion of the envelope may be produced from an element formed from glass fibres containing metal cores by etching the cores away to the required thickness, and the whole window area may then be further covered with a Lenard window, e.g. of aluminium, copper, nickel, or alumina. The channel multiplier is mounted by members 60 in close proximity to the lead or uranium photocathode 50, to obviate the need for focusing elements, and may have its channels tilted at an angle of up to 10 degrees with respect to the normal to the photocathode surface, to increase multiplication. The photocathode may contact a fluorescent screen (63, Fig. 4, not shown), sensitive to an incident X- ray, gamma ray, beta ray, or neutron image. A modified arrangement (Fig. 2, not shown), for document reproduction, employs a strip photocathode, a multiplier having a single row of channels, and a single row of windows, the charge pattern being produced line-wise by progressive line-wise exposure of the photocathode with visible light.

Filed: 1929-08-09
Abstract: 337,830. Radio Frequency Laboratories, Inc. June 8, 1929, [Convention date]. Thermionic amplifiers. -A thermionic amplifier adapted to be tuned over a band of frequencies includes a series impedance common to both grid and plate circuits, the impedance being resonant at the lower limit of the frequency band. The composite impedance, constituted by inductance L5 and condenser C5, Fig. 2, is connected between the cathode and the junction of the grid and plate circuits and is shown in parallel with a grid biasing resistor &c. The arrangement constitutes a reaction coupling between the plate and grid circuits, the effective signal voltage between grid and cathode being reduced at higher frequencies since the radio frequency potential drop across L5, C5, increases with the frequency. In a modification, Fig. 3, not shown, the inductances L5 is in series and condenser C5 in parallel with the resistor RC; the total impedance is however effectively in shunt across the resistor. Specification 294,200 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention may also be applied to audio-frequency amplifiers, and the impedance may be chosen to effect a cut-off at or near a disturbing frequency. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for playing games of skill
IPC: A63F7/02
Filed: 1924-10-20
Abstract: 246,543. Pessers, H. J. G. Oct. 20, 1924. Tivoli billiards and the like.-In game playing apparatus of the kind comprising a number of different billets adapted to receive projectiles and means for delivering a prize, ticket, token, or the like corresponding to the billet at which the projectile arrives, the delivery of the different articles upon the arrival of projectiles is effected by the movement of a common member. In the application to vertical bagatelle apparatus, a ball projected round a spiral track falls through a hole in the track or enters billets a, b, the billets a leading to a common ball reservoir 2 and the billets b to chambers 4. A ball passed to a chamber 4 operates to release a token from a cylindrical reservoir 7 corresponding to it and also to release from the reservoir 2 any balls which may be there. It then passes by a shoot 35 through a hole h back to play. The balls released from the reservoir 2 pass through another hole g to be played as required. The reservoir 2 holds two balls, a third ball arriving there falling to a shoot 6, from which it is released at the start of the game by the rocking of a crescent-shaped piece 40 after prepayment. A ball in a chamber 4 passes through a hole in a reciprocable plate 14 and rests on a concave portion 16<a> of a spring-controlled hook 16 pivoted to a plate 14. A knob on the shaft of a pinion 33, gearing with a pinion 32 having a pin and slot connection with a lever 30, is rotated thereby rocking the lever to reciprocate the plate 14. A wedge 16<c> on the plate 14 during the first part of its movement presses down the ball and engages the hook 16 with a lever 19, which is rocked to actuate the delivery slide of its particular token reservoir 7. At the same time the lever 19 by engaging a pin 29 moves a rod 24 to the right, thereby actuating a spring-controlled lever 25 to release the balls in the reservoir 2. On the return of the plate 14 to normal position the hook 16 is released from its lever 19. The plate 14 is connected to a gate which obstructs the spiral track until the plate is returned to its normal position. There is a hook 16, wedge 16<c>. and lever 19 for each chamber 4. A coin inserted in a shoot 36 tilts a lever 37 controlled by a spring 41. The lever 37 has a link 39 which rocks the piece 40 and releases a ball from the shoot 6. The balls released from the reservoir 2 are brought into play as required by a similar rocking piece operated by hand.
